zimbra logger service is not enabled! failed.

We can't tell from that isolated error what the problem is, the likelihood is that you haven't followed those steps exactly - they do work. You've given no details about the exact steps you've done nor which version (or release) of Zimbra is on the source and destination servers nor whether your DNS records etc. are correct.

I may be remembering wrong, but I thought I'd come across another migration procedure where on your 32bit and 64bit machine, you have the same version of zimbra. Copy the install from the 32bit over to the 64bit and then re-run the installer, let it upgrade things for you.

No but at the time you've posted I was in bed. It takes you two days to reply to my post and then you demand an instant answer, you do realise that these forums are Community supported and people that post here do so when they have the time?

You're still not following the correct instructions for your version of Zimbra, use the correct instructions for you version of ZCS.
